How It Works
The 20 steps map to the four stages of a used-car purchase: research, inspection, negotiation, closing. Each step has a “must” and “nice-to-have” version.
How to Use This Calculator
- Set a budget — total cost not monthly payment.
- Pre-qualify financing before visiting dealers.
- Pull vehicle history report (Carfax or AutoCheck).
- Visual inspection — exterior, interior, undercarriage.
- Road test — at least 15 minutes including highway.
- Independent mechanic inspection — non-negotiable for any car over $5k.
- Negotiate on out-the-door price, not monthly payment or trade-in separately.
- Review paperwork — title, registration, finance terms, fee line items.

| History report | Salvage / rebuilt / flood / lemon title |
| Visual | Mismatched panel paint, frame welds, odor |
| Road test | Pulling, hard shifts, dashboard lights |
| Mechanic | Frame damage, head gasket signs, transmission slip |
| Paperwork | Missing title, lien not released, odometer rollback |
Frequently Asked Questions
Should I buy from a private party or dealer?
Private party averages 10–15% lower price but no warranty, no recon, and harder financing. Dealers cost more but offer CPO, return policies and easier financing.
Is a CPO worth the markup?
For European brands (BMW, Mercedes, Audi) yes — extended warranty is valuable. For Toyota or Honda, the $2k+ markup rarely pays off.
